RAD Introduces VoIP SIP Analog Gateway for Legacy Traffic over IP-based Telephony Networks

The Vmux-310 is a VoIP SIP analog gateway designed for commercial VoIP deployment. It provides superior voice technology for connecting legacy telephones (POTS), fax machines and PBX systems over IP-based telephony networks, as well as for integration with new IP-based PBX architectures.

The Vmux-310 complies with the Session Initiation Protocol (SIP). Acting as a bridge between the PSTN and the IP network, the Vmux-310 merges phone, fax services and PBX systems with the data network. In addition, new IP-based PBX systems can be integrated into the existing architecture. The Vmux-310 dynamically and efficiently controls bandwidth allocation, leaving more bandwidth for data transport. The Vmux-310 gives customers next generation services without requiring an overhaul of existing infrastructures.

Using standard G.729A, G.726 and G.723.1 compression algorithms with Voice Activity Detection and silence suppression, the Vmux-310 provides efficient bandwidth optimization, leaving more bandwidth for data transport. It optimizes voice transmission for satellite links, pay phone networks, and centralized IVR and Quality Monitoring applications. The unit can also be deployed in MTU (Multi-Tenant Units) broadband access networks, IP Centrex and rural applications.

In addition, the product provides advanced telephony features such as long-haul, pulse metering and country-dependent MWI and CID, for true integration with existing telephony infrastructures. The Vmux-310 was designed and tested to be fully interoperable with leading soft switches and SIP servers.

The Vmux-310 VoIP SIP analog gateway is a compact, 1U high, half 19-inch wide standalone unit. It supports two, four or eight FXS ports for POTS connection, and also incorporates a 10/100BaseT Ethernet uplink. The unit is available with an AC power supply.
